But when I try to build the CCS configuration project that uses the packages built by the xdc command, I get the following error:js: "C:\CCSv4 installs\CCSv4.2.0.05010\xdctools_3_16_02_32\packages\xdc\to ols\configuro\template\compiler.opt.xdt ", line 66: Error: template generation of 'compiler.opt' failed: xdc.services.global.XDCException: gnu.targets.UNDEFINED_EXECUTABLE: 'LONGNAME' must be defined for the target gnu.targets.arm.GCArmv7A

Ack! The string you found in ITarget.xs says "config" - that means you are supposed to set it - not hack it!. Here's what I put in my config.bld to initialize (configure) for building with the A9 target:

Thank you! For some reason I missed that page, and I never realized that what I was really doing when setting the .rootdir in the config.bld file was configuring a target module's configuration parameter!

The error that the script issued makes perfect sense now that I know where to set the configuration parameter.
